Outdoor classroom: about the generation of temperature loss and first aid measures

In simple terms, a windy day may freeze at 10 degrees, and heavy rain may freeze at 20 degrees. The clothes that are saturated with sweat are the culprit. Keeping your body dry is the primary issue, followed by the right time to add energy. Avoid sweat soaking clothes, Jackets better than raincoats.

1What is the loss of temperature?

In simple terms, it is the temperature below normal questions. We all know that a fever of 37.5 degrees or more, and a temperature of 39 degrees without a decrease in body temperature will become unconscious until death. Loss of temperature is similar. If the body temperature is below 35 degrees, people will lose consciousness or even coma.

2 What condition will cause loss of temperature?

In theory, as long as the ambient temperature is lower than the body temperature, it will lead to loss of temperature. The actual situation is that people who get adequate food supplements and are in good health lose a lot of body temperature when they lose 20 degrees. If it is 10 degrees, the temperature will soon drop to a loss of temperature. In dry weather, the nude Kro is 0.78, which is basically the same as wearing a simple T-shirt. However, the cold and rain will quickly take away heat. In other words, even if the temperature is 20 degrees, the human body is exposed to the rain (no heavy rain or rain), which leads to a decrease in body temperature (the human body can quickly revert to questions by means of chills). If it is at 10 degrees, the body temperature may rapidly decrease to a state of dehydration under the rain, and the body's recovery ability cannot compensate for the balance.

3 The difference between Jackets and raincoats at this time.

Even wearing a raincoat, sweaty and wet underwear can cause the body to reduce the number of questions. This is because evaporation and convection form a cycle within the garment. At this point, breathable Jackets can reduce the accumulation of sweat. Even though the 10000 breathability also includes the loss of the DWR and the reduced air permeability, it is still possible to delay the loss of temperature compared to an unventilated raincoat.

How to first aid:

1 The body temperature must be reduced as soon as possible, leaving the wind and rain. Replace dry clothes

2 Quickly add heat. External sources of heat, such as embracing a fire. Internal heat supplements, drinking aqueous dextrose solution. Supplemental hot water (mainly due to pathological reasons, when severe temperature loss occurs, the first symptom is the reduction of blood sugar, sugar is the root of heat, liver glycogen is not decomposed in time, body temperature can not be restored. Therefore, supplemental glucose can quickly restore their ability to warm up.) Supplemental hot water is through the warm stomach to raise the temperature of internal organs so that visceral work, (the heart provides blood, the liver liver glycogen decomposition) should not rub the limb, the blood circulation will bring cold blood back to the heart, leading to cardiac arrest.

Loss of temperature symptoms:

1 chills

2 lips purple

3 Confusion
